First, take half of the coefficient of 18x then square it.

18 / 2 = 9
9^2 = 81

So, D. 81 is the answer.

Answer:

I’m pretty sure the answer is 54

Step-by-step explanation:

The top answer seemed to only do the first step in the equation but if you take 81 and subtract it by -27, the complete answer equals 54. NEVERMIND!!! after reading the question again, 81 is most likely the correct answer.

HELP ME SOMEOME PLEASE!!!!!​

Problem 1

For functions like f(x), the input is x and the output is f(x).

If x = 7, then f(7) = 12 has the input 7 and output 12.

Therefore the ordered pair is (7, 12) which is the answer

=====================================================

Problem 2

Replace every x with 3 and simplify

f(x) = 3*x

f(3) = 3*3

f(3) = 9

The input x = 3 leads to the output y = 9. Recall that y = f(x).

So (3,9) is the answer here.

Answer: 16

Step-by-step explanation:

multiplying by negative exponents can be a little tricky. So (1/4x)^-2 becomes 16/x^2 = __/x^2 so the missing number is 16

Answer:

y=1/4x-1

Step-by-step explanation:

i knew the general equation of the line and i knew the slope would be a fraction because the line is rlly flat

-1 would be the b and i plugged in simple fraction values for m

i checked in desmos and they look similar

hope this helps and is correct <3
